Can you do metal knurling in a drill press?
I have a drill press which is 220 watts. I'd like to knurl some copper razor handles with it. Is 220 watts enough power to get a good deep knurl, and how should I secure the bottom end so it is centred? Basically, can anyone tell me how I can make this work. I don't have room for a lathe. Thanks for any help.

You can offer that up to the side of the copper, and clamp it to the table. Basically, can anyone tell me how I can make this work. I don't have room for a lathe. Copper is fairly soft, so you will likely be able to knurl with a hand knurling tool. The two wheel type will be easiest since you can then push against the direction supported by the bearings. -- Cheers, John. /================================================== ===============\ | Internode Ltd - http://www.internode.co.uk | |-----------------------------------------------------------------| | John Rumm - john(at)internode(dot)co(dot)uk | \================================================= ================/ |

Thanks for any help. Knurling is done on a lathe because that is the safest way to do it. The power of the drill press is really the least of your concerns. It's quite likely, depending on the geometry of the knurling tool, and the support of the workpiece, and the retention of the chuck in the drill press, and the bearings on the drill quill, to go very wrong. But if you don't mind terminally wrecking your drill press then it is possible You'd probably need a milling machine and a boring head to make the jig to facilitate it though -- |

I can see that the piece should be supported both ends Bearings on a lathe are catering for axial and radial loads a drill press just axial ones. The chuck on a lathe is either clamped or bolted or screwed onto the spindle. In almost all operations it's not going to come loose. The drill chuck in a drill press might be just a press fit in the spindle (maybe morse taper or jacobs taper) Apply side loads (such as you'd do if attempting to mill) and the chuck and whatever it is holding can just fall out. Same load path with a knurling tool. Axial restraint of the workpiece between the chuck and the table is essential. Clamp type knurlers should be slightly safer than those approaching from one side Even a half horse motor(375W) on a lathe will easily faclitate knurling on mild steel / brass Plus copper can be a sod to machine. |

TheOtherMike - could you possibly email me? I need to talk to somebody who understands lathes. Thanks!

I, the OP, am unaware of many things hence the thread. But is the radial loading that bad with a scissors knurler? It would obviously be ridiculous to use a side knurler and push it onto the piece - the radial pressure would be far too much as above. But a scissors knurler, if the piece were held top and bottom? |

In that scenario, you'd probably be fine for a limited run. But it would *have* to be kind of knurler that puts equal pressure on both sides of the work. -- This message may be freely reproduced without limit or charge only via the Usenet protocol.

Can you do metal knurling in a drill press?
One of the things I'll have to do in my drill press is fix up some sort of live centre. I can use a MT2 part which will fit into the 19mm diameter hole in the centre of the table, but I don't know how to secure it other than wrapping some tape around it to make the 17.8mm diameter of the morse taper (at the top) fit into the 19mm hole.
Any ideas? https://www.ebay.co.uk/itm/MT2-MT3-S...53.m1438.l2649 |
